Initiate by saying "kpackagerstart UUID Some_existing_inventory_folder".
UUID is destination object where copied objects will be put at the end
as well as the object the viewer will be listening to for the next 2 commands.
Folder should be empty unless existing items there are needed in the package.
Use llOwnerSay("kpackageradd UUID1,UUID2,...,UUIDn") to add objects to list.
Call llOwnerSay("kpackagerend") to finalize and copy objects to caller.
Say kpackagerstop to stop and clear the packager.
